    I’ve just been diagnosed with osteoporosis but I don’t understand the difference between osteoporosis and arthritis. My understanding is that both affect the bones and joints. Is this correct?

    Osteoporosis: affects the bone. The bones become fragile and brittle and are more susceptible to fracturing.

    Osteoarthritis: affects the joint (the point at which 2 or more bones meet). There is degeneration of the cartilage (smooth covering over the ends of the bones). This degeneration leads to a reduction in the space in the joints which can lead to pain, stiffness and reduced joint range of motion.

    Generally speaking, osteoporosis affects the bone, and arthritis affects the joints. They are two different conditions that may co-exist.

    Osteoporosis is a condition where the bones are weak and prone to breaking. Often osteoporosis is diagnosed after a person sustains a fracture with minimal trauma (such as a simple trip and fall).

    Arthritis is a condition where the smooth articular cartilage that covers the ends of the bones is gradually destroyed. The end result is that bare bone ends rub against each other, which causes pain and stiffness at the joints. The term “arthritis” covers a variety of different conditions including osteoarthritis, rheumatoid arthritis, psoriatic arthritis and post-traumatic arthritis.

    For information about arthritis affecting the hand and wrist please visit the Melbourne Hand Surgery website.
